How to think about this
Replacement cost = current cost to rebuild your specific home with current materials + labor. Some carriers offer guaranteed-replacement-cost coverage (Chubb, PURE, USAA for members); most cap at policy limit, which means underinsurance shows up at exactly the moment you can’t afford it.
